Abstract

The invention discloses an air energy phase change material mass concrete temperature control system and a construction method thereof. The system comprises an intelligent temperature control induction regulator, a temperature control phase change material aqueous solution delivery pipeline, a phase change material dispenser, an air energy refrigeration device, a pressure pump and a filter unit. The temperature control phase change material aqueous solution delivery pipeline comprises a cooling system pipeline, a water conveying pipeline, a heat-dissipating pipe network disposed on the surfaceof mass concrete and at least one cooling pipeline pre-embedded inside the mass concrete. The design of the system is reasonable, the phase change material can be recycled, the cost is reduced, the hot melting of the circulating water is increased, and the temperature control efficiency of the circulating water temperature control system is enhanced. The cooling pipeline is buried to realize thetemperature monitoring of a single cooling pipeline. The air energy refrigeration device is additionally arranged according to the need of actual water treatment amount. The technology has universality and flexibility, and has high promotion and use value. The construction method provided by the invention has high quality of finished products.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a large-volume concrete temperature control system of an air energy phase change material and a construction method thereof. Background technique [0002] In general, concrete members with a length greater than one meter on one side are called mass concrete. After the mass concrete is poured, the hydration heat of the cementitious material in the cement base will cause the temperature to rise. In the case of a large concrete volume, the heat of hydration accumulated inside the concrete is not easy to dissipate, and the internal temperature rises, but The surface temperature is low due to the rapid heat dissipation, so it is easy to cause a significant temperature difference between the inside and the outside, causing the temperature tensile stress on the concrete surface. In the case of low early tensile strength, cracks will be formed on the surface of the mass con...
